Which statement correctly describes cryotherapy indications?

• A. It is used for chronic conditions only
• B. It is used to treat hypertension
• C. It is not effective for swelling
• D. It is used for acute injury, pain, muscle spasm, contusion

Answer: (D)

Cryotherapy is used in the acute phase of musculoskeletal problems to control inflammation and pain and to reduce muscle guarding. Cooling lowers tissue temperature, which causes vasoconstriction, slows metabolic processes, reduces nerve conduction velocity, and suppresses inflammatory mediator activity. These effects help limit edema, dull pain, and decrease muscle spasm, making the acute injury, pain, muscle spasm, and contusion combination the best fit for indications.

It isn’t limited to chronic conditions, and it’s not a treatment for hypertension. In fact, cooling can transiently raise blood pressure in some people, and hypertension is not an indication for cryotherapy. Additionally, cryotherapy helps reduce swelling rather than being ineffective for it, so a statement claiming it wouldn’t help swelling isn’t accurate.
